沒出錯，程式運行到最后一句的后面，正常退出了。uj5u.com熱心網友回復：
它沒有我想要的結果
uj5u.com熱心網友回復：
輸出成績那里就開始錯了
uj5u.com熱心網友回復：
它??說陣列那里出了點問題
uj5u.com熱心網友回復：
這個float highest ()函式有問題，修改如下，供參考：float highest ()
{
int i,m;
float high;
high = score[0][0];
for (i =0;i <N;i++)
{
for (m =0;m <M;m ++)
if (high <score [i][m])
{
high = score [i][m];
b = m;
a = i;
}
}
return high;
}
uj5u.com熱心網友回復：
再仔細看了下，void aver _cour (void)函式里面，兩個for ()回圈的條件里，M N 放錯位置了，外面for (ｉ=0；i<N;i ++)應該是N吧，里面for（m=0；m<M;m ++)應該是M 吧。轉載請註明出處，本文鏈接：https://www.uj5u.com/houduan/227970.html
